There's talk that Maicon has been unsettled over a new contract row with Inter.
Agent Antonio Caliendo told calciomercato.com: "For me it's a surprise and these surprises usually force me to ask questions. Something is happening behind him, something that I am not aware, but perhaps some of the Inter managers know more than me?
"If anyone thinks he can blackmail or force the player to sign, without the presence of their consultant, this is something very, very delicate and should not happen.
"I expect a club like Inter not to use these sort of tactics."
